Injectable 2D‐MoS2‐integrated Bioadhesive Hydrogel as Photothermal‐Derived and Drug‐Delivery Implant for Colorectal Cancer Therapy

open access: yesAdvanced Healthcare Materials, EarlyView.
An injectable, adhesive hydrogel integrating 2D‐MoS2 and 5‐fluorouracil (AlgNB/MoS2/5‐FU) is developed for near‐infrared‐triggered photothermal therapy and localized drug delivery. The adhesive hydrogel demonstrates superior tumor anchoring, efficient photothermal conversion, and synergistic inhibition of colorectal cancer progression, offering a ...

Spectrophotometry in Medicine [PDF]

open access: yesNature, 1943
THE German edition of this work was published 1 in 1933 by G. Fischer of Jena. The author, working at the Laboratory of Clinical Medicine at the University of Jena, had by then made substantial use of modern methods of spectrophotometry for investigating body fluids, and at the outbreak of the War was still publishing valuable work in this field.

Determination of Phenolic Hydroxyl Groups in Technical Lignins by Ionization Difference Ultraviolet Spectrophotometry (∆ε-IDUS method)

open access: yes, 2016
The amount of hydroxyl groups, particularly phenolic, is one of the most important parameters in lignins, as it is an indicator of lignin reactivity. Ultraviolet (UV) Spectrophotometry is a simple and inexpensive method for determining phenolic hydroxyls

SciAgents: Automating Scientific Discovery Through Bioinspired Multi‐Agent Intelligent Graph Reasoning

open access: yesAdvanced Materials, EarlyView.
The SciAgents AI model drives hypothesis generation by harnessing multi‐agent graph reasoning, extracting insights from knowledge graphs constructed from scientific papers. Each agent plays a specific role: the Ontologist defines concepts, the Scientists draft and refine proposals, and the Critic reviews.
